Answer:
The 23rd term is -187
Step-by-step explanation:
U₂₃=??, a=77, d=-12, n=23
U₂₃=a+(n-1)d
U₂₃=77+(23-1)(-12)
U₂₃=77+22(-12)
U₂₃=-187
U₂₃=-187
∴U₂₃=-187
Answer:
Hence final answer is
.
Step-by-step explanation:
Expression is not typed in proper format but as per given instruction "evaluate the exponent", I think it is:

So let's simplify that:

Apply formula x^-m=1/x^m





Hence final answer is
.
